Soulbound
I like the concept of Soulbinding items. It introduces a system of decay into a game which otherwise would have none. You find an upgrade to your equipment, the old one must be discarded or otherwise salvaged (disenchanted, sold for vendor coin, etc.). This keeps crafters in business crafting new items and it keeps farmers in business farming materials for the crafters.
However, it also seems like a massive waste. It also raises the question of what vendors do with all this vendored gear they buy that they most certainly can't sell or even wear themselves. Are they all enchanters? What do they do with those enchanting mats anyways, since they never have any for sale?
I had an idea for recycling old stuff. When gear is created, it is created as a white quality item every single time, regardless of the design. Enchanters can then enchant the gear to make it more powerful, up to a certain point. Until it is enchanted, it doesn't bind. The enchanter's magic, as a natural consequence of the magic itself, will automatically bind the item to the soul of the next person who wears or wields it in combat. If a player no longer has use of an item, they have some options. First, they can have an enchanter strip the enchantments off an item for a fee and sell the item enchantless (at which point they could use the materials, which would of course be reduced, to enchant something else). Second, they could have a Salvager deconstruct the item into its base components (minus some "waste") and sell the materials or make something else. Third, they could have the Enchanter unbind the item from their soul. This would cause the item to lose some of the potency of its enchants and become a second hand item and then sold.
I haven't decided if multiple characters per account would be a good idea, but if it were used, a second (or possibly third or fourth)hand item could be taken and have a special enchantment placed on it to turn it into an heirloom. The enchants would be set at a certain level and maybe given an heirloom only perk or two and be allowed to be left to another character on the account, or possibly given to guild members or something.
It's good to have a system which encourages trade and gathering, but second hand items could also have their own market in their own right and I think it may be worth exploring.
My next post will be about professions. I think I have a good preliminary system started that I'm working on.
